A multi-partner effort has begun to study the amount of nitrate-nitrogen (nitrate) leaching loss that occurs below an agricultural field recently converted from timber land to irrigated row crop production. The landowner has made the property and their staff available to better understand the deep drainage and nitrate leaching dynamics following this type of land use change. This study is unique.
The Discovery Farms program is a farmer-led effort to gather information on soil and nutrient loss on farms in different settings across Minnesota. The mission of Discovery Farms Minnesota is to gather water quality information under real-world conditions.
Overall Project Outcome and Results
The Minnesota Valley Trust acquired 78.5 acres of priority lands in Lincoln Township of Blue Earth County to expand the Lincoln Waterfowl Production Area for the Minnesota Valley Refuge and Wetland Management District, US Fish and Wildlife Service. Of the 78.5 acres, 21 acres were acquired with Environment and Natural Resources Trust Fund; the other 56.5 acres were acquired with nonprofit / other, non-state funds.
This demonstration sites provides information on the characteristics of agricultural drainage from a typical field in south-central Minnesota. Results will help researchers evaluate the environmental and economic impacts of specific management practices.
The goals of this site are:
Evaluate the effectiveness of nutrient and pesticide Best Management Practices (BMPs)
Evaluate different management practices and compare the environmental and economic benefits
Evaluate farm profitability using different crop management practices
